 # Changelog
 
+## v10.13.6 (2026-05-27)
+
+**Anti-Loop Resilience, Auto Token Refresh, Budget Cap, MSIX Support**
+
+### New Features
+- **Cross-session loop tracker**: Keys by user request hash — detects loops even when client creates new sessions per retry. Resets counter on new tasks.
+- **Tool-call budget**: 150 calls max per task, warning at 80. Injects directive to stop reading and write, instead of killing the session.
+- **File-path read-loop detection**: Same file read 5+ times or 30+ total file reads triggers force-finalize
+- **Auto 401 token refresh**: On 401 transient, force-refreshes Google OAuth token and retries once (both v2 + OA compat handlers)
+- **Model-aware idle timeout**: Flash/mini/haiku models get 120s timeout instead of 300s
+- **Smart compaction summary**: Directive text when read-loop detected in compacted history
+- **`_send_ag_finalize()` helper**: Returns synthetic response for hard terminations
+- **Default provider policy**: Unrecognized providers get balanced compaction (128K context, 60 items)
+- **Anti-stall self-kill fix**: No longer kills own parent process or process group
+- **Codex Desktop Updater**: Check/install/rollback/service management + manual rebuild from source
+- **E2E test suite**: `bash test-antigravity.sh --task` for real CLI task testing
+
+### Bug Fixes
+- Fix `task_retry_count` counting every turn instead of same-task retries (spam bug)
+- Fix tool-call budget killing session instead of injecting directive
+- Fix `_schema` NameError in smart-continue nudge (cobra91 PR #17)
+- Fix `_anti_stall_cleanup()` killing own parent/shell wrapper process
+- Fix OA compat path loop tracker indentation
+- Fix Codex CLI 0.134.0 profile system: separate `~/.codex/<slug>.config.toml` files
+- Fix compaction causing model loops: `max_input_items: 60→200` for 1M-token models
+- Merge cobra91 PR #17: MSIX Desktop launch, button state, `_schema` fix

 - **has_content function_call fix** (v3.11.6) — tool-call-only responses now correctly flagged as having content, preventing infinite loops on OpenAdapter/Z.AI/OpenRouter providers
 - **Vision/OCR preprocessing** (v3.11.6) — when provider rejects images, automatically calls a configurable vision fallback API (Kilo.ai) to describe images as text for text-only models; MD5-cached; retries on vision errors with preprocessed text
 - **Auth config-missing fix** (v3.11.6) — graceful handling when Codex config.toml is missing instead of showing raw os error
